Two candidates vying for City Hall are launching their own political parties to carry their names on the November ballot, sources said.

Republican Mike Bloomberg’s party’s sole platform will be education reform, and is intended to be an ongoing political organization, sources said.

Democrat Alan Hevesi is also basing his third-party line on education, said his campaign strategist, Hank Morris.

For Bloomberg, the Education First Party will be the third line carrying his candidacy if he wins the GOP primary against Herman Badillo – and may make it easier for Democratic voters, who outnumber Republicans 5-to-1, to cast a ballot for him.

For Hevesi, his education party is an attempt to stand out on a key issue with voters, in a field of four Democrats whom even he admits are hard to tell apart.
